This is simply not true, and yet it's unfortunately a very common meme among the "Don't be a dick" crowd. As a counterpoint, I'd like to share a letter we received a few months ago. I don't post stuff like this often, as it would come across as too self-congratulatory, but I do want to remind everyone that people sometimes change their minds.
For context: This guy originally wrote to us in January. He wrote that seeing the show was causing serious doubts in his own Christian beliefs. He then went on to say:
I was wondering, if there is no higher power, how you would justify morality in an atheist at all? Please don't misunderstand, as a young person on the verge of apostasy, I'm not saying that atheists have no morals, although I have met 'christians' who have claimed as much. After all, if there is no higher power, then there is no objective truth, ergo no objective morality, meaning all morality is subjective. If that is the case, then to say that a murderer is immoral is surely a fallacy, as he no doubt acted as his morals saw fit. If morality is subjective, then he is as moral for acting out the murder he saw as moral as you are for not acting out a murder you saw as immoral.
I wrote back and we discussed the morality issue for a while. The angle I took on this was the Euthyphro Dilemma, though I usually don't refer to it by name. I like to explore the concept that a God-given morality is somehow objective in a way that human consensus-derived morality is not. In the course of three more exchanges between us, and some messages from Tracie thrown in, we discussed slavery; we discussed the story of Jephthah; we talked about what kind of commands God could issue that would be considered by this person to be immoral.
After a while he said that they were hard questions but he still felt like there must be a god. The conversation petered out.
In September I received this:
Hi, Mr. Glasser,I doubt you remember me, but we had a discussion about religion and so on just under a year ago. I have since become an atheist and I thought I'd drop you an e-mail to thank you. The video I e-mailed about in the first place was the first real faith-shaking material I had come into contact with, and from there I kept investigating my religion scientifically, historically and morally. Obviously, I found it wanting and, as I said earlier, have since renounced it. I thought I'd let you know a few of the final arguments in convincing me that the bible, at least, is wrong, not really in case you hadn't heard them (I'm sure you have), but rather because, since our discussion must have been frustrating for you, I'd like you to know. One is that the God of the bible forced us into sin, and therefore knowingly and willingly condemned literally billions of people to hell by creating the Eden situation in the first place, for he knew what would happen but did nothing to change it. This is an act of incredible cruelty, and is unjustifiable, giving trouble even to my own father (a minister). That's a moral argument, I suppose, but also shows a biblical contradiction (if God is all loving and unchanging then this act (among dozens of notable others) should be impossible). The second is the fallibility of the bible. I wonder if you knew that Luke, in his gospel, lists 28 generations between Joseph, Jesus' father, and David, whereas Matthew gives 41. On top of that, the census Luke wrote about never happened, and the local census upon which it may have been based happened long after Herod's death.Those are just a few, but anyway, thanks again for showing me another way of thinking, and it's thanks in part to you guys and what you're doing that I am being fascinated and amazed every day by the way that the world works without resorting to the 'Don't ask questions, God did it' train of thought.
So. I have been asked, on a few occasions, whether arguing with people about atheism ever changes people's minds. My answer is always "Very rarely, and the changes are usually minor but positive." This is what I would consider a happy exception.
